Helical Solutions 83327 Corner Radius End Mill 5/16in 6 Flute

Product Description

The HELICAL SOLUTIONS 83327 is a 6-flute solid carbide corner radius end mill engineered for demanding material removal in stainless steel, high-temperature alloys, and hardened steels. It features a 5/16 inch mill diameter, a 0.50 mm (0.0200 inch) corner radius, and a 3/4 inch length of cut. The Tplus PVD coating provides enhanced wear resistance and thermal stability, making this tool suitable for both roughing and finishing operations in a single setup. The variable-pitch flute geometry helps reduce harmonic vibration during aggressive cuts, extending tool life and improving surface finish quality.

This end mill is designed for use in precision CNC milling applications where tight tolerances and surface integrity are required. Its primary target materials are stainless steel, high-temperature alloys (such as nickel and titanium-based alloys), and hardened steels. The single-end, centercutting design supports plunge entries and full-slot milling. It is sized for use with high-precision toolholders and is well suited for aerospace, medical device, and industrial component machining environments.

Key Features

• 6-flute variable-pitch geometry reduces chatter and supports higher feed rates in difficult materials
• Tplus PVD coating rated for stainless steel, high-temperature alloys, and hardened steel applications
• 0.50 mm corner radius protects cutting edges and reduces stress concentrations at part corners
• Centercutting design enables plunge milling without a pre-drilled entry hole
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting temperatures
• Right-hand cut, right-hand spiral flute configuration compatible with standard CNC spindle rotation

Compatibility

Designed for use with high-precision toolholders. Recommended for CNC machining centers running stainless steel, high-temperature alloy, and hardened steel workpieces. Part of the HELICAL SOLUTIONS HEV-6 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within a high-precision collet or shrink-fit toolholder to the recommended gauge-line depth before tightening. Confirm runout does not exceed the 0.0005 inch TIR maximum before beginning a cut. Always follow the machine tool manufacturer guidelines for spindle speed, feed rate, and depth-of-cut parameters when machining stainless or high-temperature alloys.
